SCOTUS ENDS COURT BATTLE OVER OBAMA'S NET NEUTRALITY RULES: The Supreme Court on Monday put an end to a legal battle over the Obama administration's net neutrality rules, refusing to hear an appeal of a lower court ruling that upheld the 2015 regulations.

The court declined to hear the appeal from the trade group USTelecom, which represents internet service providers, and Century Link Inc. without explanation.

The internet service providers, along with the Trump administration, had asked the justices to toss out the ruling from the D.C. Circuit Court of Appeals.

While the Supreme Court's order is a win for net neutrality supporters, the fight over how internet access will be regulated is still far from over.

The FCC voted 3-2 along party lines last December to repeal the rules, a decision that is facing a separate challenge from net neutrality supporters before the D.C. Circuit. The repeal went into effect in June, and Monday's order will have no immediate bearing on the current state of the rules.

But net neutrality supporters celebrated the win on Monday, noting that it leaves in place a high court ruling that the FCC has the authority to regulate broadband like a public utility.

WHAT THE CYBER AGENDA MIGHT LOOK LIKE AFTER TUESDAY: The midterm elections will be the first major test of election security since 2016, and also set the stage for the next Congress's cyber priorities.

FACEBOOK WON'T LET GOP PROMOTE TRUMP AD: Facebook on Monday said it would not run President Trump's controversial immigration ad, which critics have labeled racist, on its website.

"This ad violates Facebook's advertising policy against sensational content so we are rejecting it," a Facebook spokesperson told The Hill in a statement. "While the video is allowed to be posted on Facebook, it cannot receive paid distribution."

While Facebook won't let the video run as a paid ad, it will be allowed on the social media giant's platform under the company's community standards.

The spokesman confirmed that Facebook initially approved the ad.

According to a review of Facebook political ad data, the Trump campaign spent between $28,000 and $100,000 to run the ad, which was displayed on the platform between 2.8 million to 5 million times.

The ad focuses on an undocumented immigrant who was deported several times before coming back into the U.S. and killing two police officers.

The man, Luis Bracamontes, was arrested and released in 1998 by Republican Maricopa County, Ariz., Sheriff Joe Arpaio and then deported twice, once during a GOP president's administration and once during a Democrat's, despite the video's claim that Democrats allowed Bracamontes to stay in the U.S.

YIKES! Hackers have attempted to breach U.S. election systems more than 160 times since August, according to a federal election threats report viewed by The Boston Globe.

Department of Homeland Security (DHS) reports show that foreign hackers have made dozens of new pushes to try to access U.S. election systems, like voter registration databases, in the weeks ahead of Tuesday's elections, the Globe reported on Monday. Officials have publicly said that they have been able to prevent cyberattacks on election systems.

A DHS cybersecurity official told the Globe that the hacking attempts are similar to those used by Russia ahead of the 2016 election, but that they have not yet attributed the attacks to any one foreign entity. "We're seeing the same thing; the only difference is now we aren't saying Russia," the official told the newspaper.

The DHS report states that the hackers have had "limited success." For example, a senior official leading a state's election systems saw their personal social media account hacked on Oct. 23. It was then reregistered with a Russian email account, according to the Globe.

DHS spokesman Scott McConnell said in a statement to The Hill that state and local election officials are sharing more information about the kind of cyberattacks they are experiencing.

"This does not mean that our partners are seeing an increase in cyber threats to their networks," he said. "DHS is committed to sharing timely and actionable information, like what is outlined in the intelligence report, with our elections partners."

McConnell said the strategies being used by cyber actors are "common and not unique to election systems.

GAB BACK ONLINE: Gab, which was booted by its domain host after a user of the platform was accused of killing 11 in a Pittsburgh synagogue, came back online this week.

The platform, which bills itself as a free speech alternative to Twitter, has been scrutinized for attracting far-right, white supremacist and neo-Nazi users who have flocked to its platform after being banned from mainstream sites like Twitter and Facebook.

The scrutiny hit a climax in the aftermath of last month's tragedy in Pittsburgh when the company PayPal said that it would no longer provide service to the site and Gab's web host, GoDaddy, also decided to drop it, effectively taking the platform offline.

YOU GET HQ2... AND YOU GET HQ2: Amazon is planning to split its second headquarters between two cities, The Wall Street Journal reported Monday.

A person familiar with the matter told the Journal that the decision was driven by the need to recruit enough tech talent.

The source also said it will spread the impact of the second headquarters, known popularly as "HQ2" across two communities, easing potential housing and transit problems caused by a sudden influx of tens of thousands of workers.

The person said 25,000 employees will go to each city the company selects, and an announcement of the two locations could come as soon as this week.
